Valve.



UNITED STATES PATENT FFIQ@ HENRY LIPPOLI), OF ERIE, PENNSYLVANIA, ASSIGNOR TO LIPPOLD VALVE COMPANY, OF ERIE, PENNSYLVANIA, A CORPORATION OE PENNSYLVANIA.

VALVE.

To all whom it may concern:

Be it known that I, HENRY LIrroLD, a citi- Zen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

Valves closing with a disk, especially check valves, are apt to become foul so that the seats are injured. It has been recognized that this difficulty might be obviated to a large extent by causing the disk to rotate, and various devices have been designed for this purpose.

The object of this invention is to provide a more efiicient means for effecting the rotation of the disk.

The invent-ion is illustrated in the accompanying drawing as follows:

Figure l is a central section of the valve constructed in accordance with my invention. Fig. 2 a bottom view of the valve disk and rotating vanes.

l, marks the body of the valve; 2, the inlet; 3, the outlet; 4, the diaphragm. These are of the usual construction.

The diaphragm is provided with a passage 5 the axis of which is at right angles to the inlet and outlet and in which is arranged the removable seat 6; the valve disk 't' has the seat contacting portion 8 for operating upon the seat 6, and stem 9 extends upward from the valve into the socket 10 in bonnet ll.

The vanes 12 extend downwardly from the disk 7 in the passage 5. These vanes are deiiected from a direction radial to the axis of the disk so that with a movementof fluid past the disk in a direction lateral to the axis of the disk, there is delivered to a vane on one side of the disk a greater pressure than is delivered to a vane on the opposite side of the disk, and in consequence the disk is rotated through the action of the laterally moving iiuid past the disk.

viewed in Fig. 2, the vane on the right receives a greater pressure from the lateral flow of liquid than the vane on the left, and in consequence as the liquid passes through the valve, the disk is rotated. This rotation occurs by reason of the lateral movement of the liquid relatively to the axis of the disk.

It will be observed that if the disk is lifted the liquid moving through the passage 5 at the side toward the inlet will, when it reaches the upper part of the passage, move toward the outlet-in other words, laterally to the axis of the disk, and this will rotate the valve. 0n the other hand, the incoming liquid has a movement as it enters the passage 5 from that side of the axis of the passage 5 nearest the inlet toward that side of the axis of the passage 5 nearest the outlet. This lateral movementof the liquid is more pronounced when both the inlet passage and the outlet passage are at right angles to the axis of the passage 5. With either of these passages arranged at right angles to the axis of the passage 5, there will be a lateral movement of the liquid and a consequentrotation of the valve.

What I claim as new is:

l. In a valve, the combination of a body having inlet and outlet passages; a diaphragm with an opening through it, and a seat upon it, the axis of said opening being at an angle to one of said passages; a disk operating uponsaid seat; vanes on the side of the disk toward the inlet of the valve, said vanes being deiiected from a direction radial to the axis of the disk, whereby aI greater pressure is exerted upon the vanes at one side of the disk than at the opposite side of the disk, and the disk rotated by a moyement of fluid laterally to the axis of the dis I.

2. In a valve, the combination of a body having inlet and outlet passages; a diaphragm having an opening therethrough, and a seat upon it, the axis of said opening being at an angle to both of said passages; a disk operating upon said seat; vanes on the side of the disk toward the inlet of In testimony whereof I have hereunto set the valve, said vanes being, deflected from a 'my hand in the presence of two subscribing direction radial to the axis of th disk, Witnesses.

whereby a greater ressure is exerte upon Jthe Vanes at one sidlgJ of the disk than at the HENRY LHDFOLD' opposite side of the disk, and the disk r0 Witnesses:

tated by a movement of fluid laterally to the E. B. EAGLES,

axis of the disk. i H. C. LORD.
